Edge Type Does Not Have a Node Type as Its From Source

Erroneous Code Example

This error occurs when you try to use an edge in a context that requires the From type to be a node, but the edge’s From type is not a node.

queries.hx

QUERY getConnections(id: ID) =>
    doc <- V<Document>(id)
    connections <- doc->Related
    RETURN connections

Solution

Ensure the edge type has a node type as its From source, or use the appropriate traversal for vector types.

schema.hx

N::User {
    name: String,
}

E::Follows {
    From: User,
    To: User,
}
